Answer part A and B In many chemical reactions of two or morecompounds, ions are present in the solution that donot participate in the reaction. These ions, knownas spectator ions, can be removed from thechemical equation describing the reaction. Achemical equation that has the spectator ionsremoved is known as a net ionic equation.Reactions between ionic compounds often result inthe precipitation of an insoluble compound.Spectator ions and precipitation products of achemical reaction can be predicted by consultingan ionic substance solubility table. Here is one suchtable:Compound ofLi+, Na+,K+, or NH4+NO3 orC₂H3O2Cl, Br, orISO42-2-CO3²- orPO433-OH or S2-RuleAlways solubleAlways solubleInsoluble with Ag+, Hg₂+, orPb2+. Soluble with any otherion.Soluble with all the ions excitSr²+, Ba²+, Ca2+, Ag+,Hg₂2+, or Pb²+Soluble with Li+, Na+, K+, orNH4+ Insoluble with anyother ion.Soluble with Ca²+, Sr²+Ba2+, Li+, Na+, K+, orNH4+. Insoluble with anyother ion.Entering chemical equationsWhen entering chemical equations, please follow the following formatting guidelines• Add phases to all chemical reactions unless asked otherwise. When adding phases, make sure not to placethem as a subscript.• Do not stack charges and subscripts. To add a charge to an ion with a subscript, first enter the subscript. Forexample, to type SO42- start by typing SO4. Then use the arrow key to arrow over before adding asuperscript with the charge.If you make a formatting error, you will see an message such as "Check your placement of subscripts and superscripts." or"There is an error in your submission. Make sure you have formatted it properly." You will not lose any credit, but the answerwill need to be edited and re-submitted.Part AWhat is the net ionic equation of the reaction of ZnCl2 with NaOH?Express you answer as a chemical equation including phases.► View Available Hint(s)0SubmitΑΣΦA chemical reaction does not occur for this question.▾ Part B?What is the net ionic equation of the reaction of MgSO4 with Pb(NO3)2?Express you answer as a chemical equation including phases.▸ View Available Hint(s)ΑΣΦ?

On Easter Sunday, April 3, 1983, nitric acid spilled from a tank car near downtown Denver, Colorado. The spill was neutralized with sodium carbonate: 2HNO3(aq)+Na2CO3(aq)2NaNO3(aq)+H2O(l)+CO2(g) a. Calculate H for this reaction. Approximately 2.0 104 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO3 by mass with a density of 1.42 glcm3. What mass of sodium carbonate was required for complete neutralization of the spill, and what quantity of heat was evolved? (Hf for NaNO3(aq) = 467 kJ/mol) b. According to The Denver Post for April 4, 1983, authorities feared that dangerous air pollution might occur during the neutralization. Considering the magnitude of H, what was their major concern?

Apply Students conducted a lab to investigate limiting and excess reactants. The students added different volumes of sodium phosphate solution (Na3PO4) to a beaker. They then added a constant volume of cobalt(ll) nitrate solution (CO(NO3)2) stirred the contents, and allowed the beakers to sit overnight. The next day, each beaker had a purple precipitate at the bottom. The students decanted the supernatant from each beaker, divided it into two samples, and added one drop Of sodium phosphate solution to one sample and one drop of cobalt(ll) nitrate solution to the second sample. Their results are shown in Table 11.5. a. Write a balanced chemical equation for the reaction. b. Based on the results, identify the limiting reactant and the excess reactant for each trial.
